Number of Solutions from a Graph

Use the graph to find all the possible solutions on the line y = -2x + 3. Then choose the correct answer.

•   (2, 0)  (1, 2)  
        (4, -4)  (-3, 10)

•   (3, 11)  (-2, -4)  
      (1, 5)  (-1, -1)

•  (0, 1)  (1, 6)  
        (1, -2)  (10, -16)

•   (-1, 5)  (-3, 9)  
       (1, 1)  (6, -9)

How many solutions does the following system have? Why?
y = -2/3x + 5
2x + 3y = 15

• None.  The equations have the same slope and different  
  y-intercepts

• Infinitely many.  The equations are exactly the same when in slope-intercept form.

• Three.  There are two equations so there are exactly three solutions to the system.

• One.  The equations have different slopes so there is exactly one solution.
